noiose@ npplcnton Be it lrnown that; l, FREDERICK Wimmer BRAMP'ION, a subject of the llingl of Greet Britain, residing at Kidderminster, Enggd lend, have invented new and useful linprovements in Wheels for Motor snclother "Veliik cles, of Which the followeng is especification.

This invention comprises improvements in and relating to Wheels for motor enel othei` vehicles and has for its object to pron vide sn. eective tubular spoke Wheel.

Wheels built up Wit-li tubular spokes secured by metal centers and with steel rims lieve advantages in lightness and strength. which render them desirable if the)I een be produced in s manner insuring the'sbsolute 4rigidity :ind` security of the bracing of the spokes at :the Wheel'oenter.

My invention enables s rigid snol secure bracing tobe effected md provides s light strong Wheel.

ln' accordance with the invention employ two cupped .shells for the Wheel center in each of which thelange is formeel or providel with s series'oi notches or gaps to embrace the spokes. The spokes form s lit in the notches or gaps of the flanges when the shells are separated to some extentsmi the shells Aaire then closed together under considerable pressure, thus the jaws 'forine bythe gapped flanges bite into the spokes and the shells areA riveted or otherwise se cured in this position. A

l prefer to shape the ends of the spokes so that they form s solid ring of inetel st Wheel centekgso that the complete Wheel has greet advantsgesAin strength under lood or shook.

Esch flange is gsppe or notclieol es et d enel each `oi? the gaps or notches follows the contour of s spoke but is preferably rather less than hell? the cross sectional eres. of same :it the port Where it will embrace it. The shells are tesmed with e central opening es shown. l

Age-inst the ring' of metal formed by the Wedge parts e oli' the spokes l prefer to place on each side a metal ring j Whose outer elige shuts against the shoulder g'formefl by the lening of the spoke.' Against the outer .tsce of esch of the'ring'sf the rings are fivetecl to the spokes hy the rivets f. l srrenge :1V psd ,t of Woocl or other suit-sole materiel and the shells come against these pods snel inclose the Whole. @Wing to the gaps or notches 5 of the flanges of the shells o being Iless than heli the cross seetionsl aree of the los spokes whose contour they tit there is a gap between the edges ofthe flanges when the shells are fitting tight against the spokes a and the wood pads zA as shown at Fig. 4l. The wheel is then placed in a press'and the shells are forced up together thns compressing the pads jl, and'biti-ng by means of the flanges c' into the spokes a. In this condition the"parts are riveted or otherwise secured togetlier but countersunk headed rivets i are preferably used. The ends of the spokesv may be connected to any suitable rim j in any desired manner, that. shown on the drawing at. Figs. E2, 8, and E) is an example only. In this example a plate 17.1 with a eentral hole which has a sunk margin is fitted onto the end of the spoke and is brazed or Welded thereon and the plate is riveted or otherwise secured to the rim I prefer to carry the spoke end through flush with the back of the plate so thatY there is a. direct abutment of the spoke end against the rim. IVith a wheel built up in this way absolute rigidity of the center and the spokes is obtained for as will be understood the biting of the flanges c into the spokes is a security that is not affected by the wearing of rivets or other slackness that `may occur in built np wheels after long use. ln addition to: such security as is given by the biting in of the flanges c it will be observed from Fig. 0, that the wedging of the ends of the spokes so that they form a complete ring of metal forms a second secure fixture of the spokes againstany movement around the wheel'center. The rivets also are a security against such movement. Laterally there is the grip of the flanges on the spokes and the firm mounting caused by the compression on the pads h and the support given by the rings f. Compression strains on the wheel are taken by the grip of the flanges on the spokes, the abutment of theshoulders on the rings f and the direct bea-ring of the ends of the spokes on the hub or on a sleeve around same for as will be seen from Fig. Q, the spokeends are flush with the central margins oflthe rings f the Ypads y] and the shells so that the. rivets?v are largely relieved.v of strain. rIensional lstrains yare takeny byl the-"shoulders formed by the tops of the wedge parts of the spokes bearing against the undersides of the flanges a' of the-shells, and by the flanges gipping into the spokes as before described.

In the modification shown at Fig. l0 the ends ofi the spokes a within the shells Z) are not flattened but are of `oval form through .out and meet one against the side of the other upon an eyelet or short sleeve Z which passes through the shells t; and is expanded into countersnnk margins of the shells as at Fig. l1. The Spokes are preferably fitted with, a liner m, see Fig. 10, and may have at hard WOOd filling also. A. rivet n may pass through each spoke and the shells may be secured together by rivets i as in the previous example but in this example the rivets are spaced between the spokes. If desired tlu` space between the spokes may be filled with hard wood blocks or any other suitable filling. It will be understood that in this example the compression of the. side shells f' onto the spokes is followed in the. same wav as the previous example.

lu the further modification shown at Figs. l to 15 the flanged shells /1 are used and gripped on the spokes exactly as before..

'Ine spokes are flattened at their inner ends but at right angles tothe direction of tlat-v toning shown at Figs. 1 Ito 7, that is to say in the present case the flattening is vin the plane of the greatest width 'ofi the oval and this flattening is arranged transversely between the shells as shown. Thespoles are preferably drilled before flattening and a rivet 'n is inserted in the hole and thespoke is then flattened `in dies which press the metal of the sides of the oval together eX- eept at the rivet. where it is pressed around it as shown at Figs. 14 and 15. Thespoke is held in the dies so that the sides of the flattened part are not free to expand rpast the side margins of the oval or they may be allowed to expand j ust past' such margins as here shown. l which bear against. the flanges c of the shells Z) to relieve the rivets of tensional strains.`

The rivets n are riveted over flush with thefaees of the shells b lwhen the latter are pressed into the spokes. IVhena shoulder This then forms shoulders o l o is formed on thespokes the gaps d in the flanges o must not be cut right to the ,inner faces of the shells but af distance short thereof corresponding to the shoulder. The spaces between the spoke ends are filled; with hard wood or other filling p and ,the rivets arev passed through the shells as. before.

In all the examples I may provide. thel inner ends of the spokes with the liners m for strengthening Athem or I may` use a heavier gage of' metal for the whole spoke. The metal usedfor the Wheel ispreferably steel so atV the spokes and shells may'.

be light `rile giving great strength.

What. I claim and desire'to secure by Letl ters Patent then is:

l.. A wheel havingl in combination a rim, tubular spo-kes extending from said rim to a wheelcentenvsaid spokes being flattened: to a wedge at their inner ends7 which wedge parts fit each other to form a ring at the wheel center, a pair of rings, said rings bracing said wedge parts of said spokes, anda pair of flanged shells, saidshells inclosing said rings and biting by means of their flanges into the spokes above said rings.
